Get ready for another late-summer blast from the furnace next week.

Forecasters are saying the high temperatures and humidity this week that pushed the heat index into the 100s, look to return by the middle of next week and stick around for a little while.

Philadelphia public school students had half-days Tuesday through Thursday this week to keep them safe from the heat, as many classes lack air conditioning. Tens of thousands of students across the Philly region will end their summer vacation and return to school next Tuesday, just in time for the return of swelter.

According to Weatherboy.com, the hottest temperatures and most excessive humidity will set up midweek along the I-95 corridor.

Said the weather site:

Combined with high humidity values, the first 10 days of September may feel more like what one would expect during the first 10 days of August.

According to the National Weather Service, high pressure will remain dominant through most of next week, with chances for rain and thunderstorms each afternoon, including the Labor Day holiday. That ridge of high pressure will continue to strengthen through the week, with potential for above normal temperatures. High dew points will result in heat indices in the mid-to-upper-90s, probably through next Friday, when another cold front is expected to arrive, forecasters said.

Meanwhile, a chance of showers and a few thunderstorms are likely in the afternoon and evenings through the holiday weekend.

Here's the 7-day forecast from the weather service for Philadelphia, the Jersey Shore and the Poconos:
